      With non-reactive REST Client (quarkus-rest-client), it is possible to do this:

      public class Data {
    public String foo;
    public Integer bar;
}

      public class MultipartBody {
    @FormParam("data")
    @PartType(MediaType.APPLICATION_JSON)
    public Data data;
}

      @Path("/echo")
@RegisterRestClient
public interface MultipartService {
    @POST
    @Consumes(MediaType.MULTIPART_FORM_DATA)
    @Produces(MediaType.TEXT_PLAIN)
    String sendMultipartData(@MultipartForm MultipartBody data);

}

      However, the same does not work with REST Clent Reactive (quarkus-rest-client-reactive).
      Invoking the client will result in an error:

      ...
